From the feed rolls 95 the sections a pass to the edge conditioning orfinishing mechanism 4 I having a plurality of sets of devices, one setfor each section a, two sets being herein shown and indicated at I03,l63a. As the sections a are in edge to edge relation when slit, the setsof devices I09, lllia, are so arranged that they may condition, finishor round the side. edges of both sections simultaneously, whileproviding for the conboth sections are guided to and fed in spacedplanes above and below the plane in which the material moves through theleveling mechanism 2 and trimming and slitting mechanism 3, and the setsof edging devices are in these spaced planes, respectively. The sets ofdevices I03, I030, are positioned in different horizontal planes andspaced longitudinally of the material as shown in Figs. 2, 4 and 6 or inthe same transverse plane as shown in Figs. 22, 23, 24 and 25.

. Referring to Figs. 2, 4, 6, 16 and 1'7, I indi-' cates standardssuitably mounted on a base Ililla. I08 indicates a U-beam having endwalls suitably secured to the standards I04. I01, I01, indicate a pairof supports provided on their opposite sides with lugs removably andadjustably secured to the sides of the beam I06, for supporting one setof finishing or edging devices (set I 03) Each support isformed with anopening I 08 and its plane. Each section a as it leaves the trimming.and slitting devices is rough and provided with burs, so that bypassing the section to and between a pair of edging devices the metal ofthe edges is finished, smoothed, conditioned or rounded as may bedesired, to eliminate the roughness and burs and condition them forwelding or other purposes, As shown in Fig. 20, the edges of the sectionmay be finished to be disposed at right angles to the surfaces thereofor, as shown in Fig. 21,. these edges may be rounded. By preference, I,associate with the edging devices a pair of holders I I0 which engagethe upper and lower surfaces of the section to prevent distortion orbuckling of the section while being engaged by the edging devices. Inthe form of construction shown in these views, the holders comprise apair of freely rotatable rolls H0. The axes of the rolls III! aredisposed in the plane cutting the axes of the edging devices I001). Therolls IIO are provided at their opposite, ends with stud shafts whichloosely rotate in bearings provided in the upper and lower walls of thesupports I01. III, H2, indicate pairs of driven feed rolls disposedforward and rearward of the set of edging devices I03 and serving toguide and feed the section in the plane of the grooves in the devicesI03b'. From the feed rolls N2 the section a passes to and between a Yindicates a worm gear in mesh with a wornfixed -to the shaft 84. Theworm gear- H4 is fixed to a shaft I I5 carrying a pinion 5a which is inmesh with a gear H6, the gear in turn being fixed to a shaft I IBa (seeFig. 4 The shaft litia is connected through a coupling III to one end ofthe shaft of a guide and feed roll IIB to which reference will later bemade. The opposite end of the shaft for the roll H8 carries a gear HS(Fig. which meshes with a gear I22 fixed to the upper feed roll III. Thegear I meshes assaesa with a gear I20a fixed to the shaft for the lowerfeed roll I i I and the latter gear, through an idler I2I drives a gearI22 fixed to the shaft for the lower feed roll 2. The gear I22 mesheswith a gear I22a fixed to the shaft for the upper feed roll H2.

The other section a of the material is. guided and fed by the roll II8(already referred to) and. a plate I23 to the set of edging devicesI03a. The

plate I 23 is mounted on a cross bar I23a secured at its ends to thestandards 04. The set of devices IBM is arranged in a plane above theset I03 and spaced longitudinally of the direction of feed of thematerial, but in alinement with the adjacent section a. The set ofdevices Ilila comprise opposite related edging devices constructed andmounted similarly to the set of devices I63 already referred to, toengage the opposite edges of the section and have associated with themholders III! which engage the adjacent section a in line with the edgingdevices, these rolls being constructed and mounted in the same manner asthe rolls III). III, II2, indicate pairs of feed rolls disposed forwardand rearward of the set of devices I03a. The feed rolls III', 2', aremounted similarly to the rolls III,.

H2, and are driven as follows (see Fig. 15): I20 indicates a, gear fixedto the shaft for the lower feed roll III and in mesh with and driven byv the gear I22a. The gear I24 also meshes with a gear I24a fixed to theshaft for the upper feed 'roll III and with an idler I25. The idler!meshes with a. gear I26 fixed to the shaft for the lower feed roll 2'and the gear I26 in turn meshes with a gear I260 fixed to the shaft forthe upper feed roll 2'. The gears above referred to are enclosed in .asuitable casing I21 (see Fig. 4).

Figs.- 22 to 25, inclusive, show a modified form of construction inwhich the sets of edge finishing devices, the adjacent alined rolls andthe front and rear feed rolls for each set are disposed in the sametransverse plane but spaced in different horizontal planes in alinementwith the sections a, respectively. In this form of construction thestandards may be formed in sections 104:, lfllz' (see Figs-23 and 25).The upper set of edge finishing devices I03z and the alined rolls andthe front and rear feed rolls are similar to like parts alreadydescribed and the corresponding parts of the lower set I031." and theparts associated therewith are also similar to those already referredto, except that the upper feed rolls IIIr, Il2x,are not adjustablymounted, whereas the lower feed rolls iIIx, 2a: are adjustablevertically. The journal boxes for the upper-rolls II Ir, 2.1:, fit intoopenings I20 and rest on lugs I28 fixed to the outer walls of thestandards and are held thereon by lugs I280 fixed to and depending fromthe flange IZBbof the upper standards I040? which is suitably bolted tothe lower standards Iiitx. The journal boxes for the shafts of theselower feed rolls slidably fit the openings I28 in the standard sectionsI041; and engage wedges I28" which are operable in ways at the lowerends of the openings and when moved endwise raise or lower the adjacentjournal boxes. Each wedge I28" is constructed to rotatably butnon-slidably support a shaft I29, shaped at its outer end to take asuitable tool to effect a rotation of the shaft and provided at itsinner end with threads and engaging a threaded opening formed in theadiacent standard section, whereby rotation of the shaft I29 will eflectmovementlof the wedge is.

either direction. In this form of construction, the shafts for each'pairof feed rolls are drivingly connected by "gears I33, I3I, respectively I(see Fig. 23). The gears I3I connected to the shafts for the lower feedrolls related to the upper edge up-setting devices are in mesh with anddriven by an idler I32 which is driven by a gear I33. The gear I33 is inmesh with and drives the gears I33 connected to the shafts for the upperfeed rolls related to the lower edge upsetting devices. The gear I33 isfixed to a drive shaft I34. The shaft I34 may be connected to the drivenshaft 84 as ah'eady set forth in connection with the shaft IIIia ordriven by a separate motor,

The re-coiling mechanism comprises the following: I35 indicates a pairof spaced standards mounted on a support or base I35a. I33, I31, I33,indicate a set of driven rolls between which the sections a, a, feed inside by side 'relation (see Fig. 5), these rolls being so arranged thatthey co-operate to bend or curve the sections as this feeding takesplace. The shafts for these rolls are suitably mounted in journal boxesmounted in the standards, the boxes for the shafts of the.rolls I31;I33, respectively, being adjustable to insure the desired curvature, sothat the sections, will readily wind into coils A, as shown. I 39indicates a bed mounted on the base I35a forward of the standards I35.At

its opposite ends the bed is formed with upstanding lugs I40 havingopenings to receive and support a rod or shaft I4I, on which is pivoteda shelf I42. The shaft I4,I supports a roller I43 mounted on the outerend of the shelf I42, to support the coils A. As the rollers I43, I44,are free to rotate, they permit each coil to rotate about its axis dueto the feed of the section a from the rolls I36, I31, I38. The shelf I42is supported at its outer end by a pair of screws I45'threaded throughopenings formed in the The screws I45 are provided with hand wheels I46for rotating them to swing the shelf upwardly to a desired position toaccommodate the coil when the first convolution thereof is produced. Asthe coil A increases in diameter, due to the progressive coiling action,

the shelf I42 may be adjusted downwardly to able gearing in a casing I41by ashaft I43, the

shaft being driven through reducing gears I48 by a shaft I50, which inturn'is driven through a worm and worm gear by the shaft I5I of a motorI52.

It will be understood that the driven elements of each mechanism havethe same peripheral speed and that these elements of all the mechanismsare driven at speeds which insures a uniform feed of thematerialtoprevent slack or buckling thereof while-passing from one mechanism tothe other.
